Plastic Injection Sprue Gates

Gate Cosmetics

Gate Cosmetics
Figure “A” shown here depicts a large scar left from cutting or machining the sprue gate. Therefore, it is important to gate into a non-cosmetic area or surface that will not affect the part function. Other cosmetic problems are possible flow lines radiating out from the sprue, and/or sink marks opposite the sprue.
